Abstract

A subscriber terminal using a method of controlling initial power ramp-up in CDMA systems by using short codes is disclosed. The subscriber terminal includes having its transmission power regulated, with means for transmitting a periodic signal at an initial predetermined power level and repeatedly retransmitting the periodic signal each retransmission occurring at successively higher power levels; means for receiving a confirmation signal, and means for terminating transmission of the periodic signal in response to the received confirmation; means for engaging in a closed loop power control procedure to regulate the subscriber unit transmission power, after the periodic signal transmission terminating; and means for transmitting a call signal. The subscriber terminal using a method of controlling initial power ramp-up in CDMA systems by using short codes is particularly useful for overcoming the problems of power overshoot and interference to other subscriber stations known in the art and to provide for a base station to quickly synchronize to the spreading code used by the subscriber unit.
